This invention relates to inhalation devices and, more particularly, to a prophylactic inhalation device for use by persons with obstructed and/or blocked nasal passages.
People with obstructed and/or blocked nasal passages may experience sleep deprivation due to such conditions. The obstructed/blocked nasal passages may be due to physical conditions or may occur after nasal operations after which the nasal passages are temporarily packed (≈five days) to control bleeding and provide support thereto. As such the patients must necessarily breathe through their mouth during such blockages.
Sleep deprivation occurs in such instances primarily due to the patient's fear of suffocation which arises upon mouth closure. Upon sensing a mouth closure the patient awakes and may find it difficult to sleep because of the fear of subsequent mouth closure. Such fear may become so pronounced that sleep may become impossible. Thus, hospitalization could result so that the distraught patient may sleep in a monitored environment.
Furthermore, upon swallowing discomfort of the patient may occur. As the act of swallowing is normally accompanied by mouth closure, air is removed from the oral and/or nasal cavities. Thus, a partial vacuum may be produced due to the blocked nasal passages. This vacuum causes discomfort of the tissues of the nasal passages particularly if the tissues are experiencing trauma due to an antecedent operation.
Finally, as the patients must breathe through their mouths the incoming air is not conditioned by the nasal passages. The throat and lips may become parched leading to more discomfort. Thus, one or more of these factors can lead to patient discomfort and sleep deprivation.
Various devices have arisen to assist patients in breathing. However, such devices have been relatively expensive, cumbersome to use and have not cost-effectively addressed the above problems.
In response thereto I have provided an inhalation device designed to be comfortably worn and maintained in place by a sleeping user. A mouthpiece assembly presents a bite plate and a downstream humidifying chamber positioned outside the wearer's mouth. The humidifying chamber encompasses a plurality of cones designed to capture moisture molecules for transfer of the moisture to an air stream passing through the chamber. The mouthpiece includes structure which displaces the dental arches so as to preclude a vacuum buildup within the oral cavity upon swallowing. Accordingly, the device addresses the major factors leading to sleep deprivation of a user experiencing nasal problems.
It is therefore a general object of this invention to provide a device to assist the inhalation process of a user having nasal obstruction and/or blockage problems.
Another object of this invention is to provide a device, as aforesaid, which precludes mouth closure of the wearer to reduce the accompanying sensation of suffocation.
Still another object of this invention is to provide a device, as aforesaid, which diminishes parched lips and diminishes parching of the throat.
A still further object of this invention is to provide a device, as aforesaid, which precludes the discomfort associated with swallowing.
Still another object of this invention is to provide a device, as aforesaid, which humidifies the inhaled and exhaled air streams.
Another object of this invention is to provide a device, as aforesaid, having a mouthpiece which is effectively retained adjacent the upper and lower dental arches of a user.
Still another object of this invention is to provide a device with mouthpiece, as aforesaid, which effectively displaces the dental arches of the user so as to inhibit production of a vacuum in the oral cavity upon swallowing.
A further object of this invention is to provide a device with mouthpiece, as aforesaid, which inhibits the entry of untreated air into the oral cavity.
Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

FIG. 7 is a plan view of the bracket of the supplemental fastening device.
Turning more particularly to the drawings, FIG. 1 illustrates the sleep aid device 10 as generally comprising a mouthpiece assembly 100 and an air treatment assembly 200. The mouthpiece assembly 100, preferably made of a flexible material, generally comprises an arc-like plate 102 having a pair of bit elements 104 extending therefrom. An oval aperture 106 presents an air outlet 106 centrally located within the plate 102. Each bit element 104 comprises a post 105 with a lug 103 at the free end thereof. The posts 105 are adjacent the lateral ends of the plate 102 to preclude interference with incoming air being discharged from the outlet 106 and into the oral cavity.
The plate 102 configuration conforms to the shape of the front surface of the upper and lower dental arches. The plate 102 is preferably designed to bear against the front surface of the dental arches and primarily upon the upper incisors. Upon placement of the plate 102 against the dental arches the posts 105 extend between the first molars of the upper and lower dental arches. This post 105 extension positions the lugs 103 adjacent the inside surface of the dental arches behind the molars. Thus, the bit elements 104 preclude full closure of the dental arches while maintaining the plate in place. Accordingly, no significant vacuum can be produced in the mouth during swallowing which diminishes the above-described patient discomfort.
Upon placement of the mouthpiece 102 against the front surface of the dental arches the user's lips extend about the plate 102. The lips then rest in the indented annular crevice 220 extending about the primary air chamber 202. Thus, the lips form a seal around the annular crevice 220. This seal precludes passage of outside, untreated air between the lips, around plate 102 and into the oral cavity. As only treated air, as to be subsequently described, will be allowed to enter the oral cavity the above-described lip parchment and throat parchment problems are diminished.
The air treatment assembly 200 comprises a primary air housing 202 having an internal primary chamber 210 therein which surrounds the plate 102 aperture 106. Chamber 210 is in communication with a first channel 212 defined by interior and exterior apertures at the ends thereof. The housing 202 is preferably made of a relatively non-flexible material so as to allow attachment of the assembly 200 to downstream medical devices.
A humidifier housing 250 is configured to slide into the first channel or sleeve 212 of the primary air housing 202 and is held therein by a friction fit relationship therebetween. The degree of extension of the humidifier housing 250 within the channel 212 is defined by abutment with the annular shoulder 262. Accordingly, the humidifier housing 250 is releasably engageable within the channel 212.
Within the humidifier housing 250 is a second channel 252 as defined by exterior 254 and interior 252 apertures. The channel 252 contains a series of paired, opposed cones 280, 282, 284 radially extending about the channel 252 and longitudinally spaced-apart therealong. Each pair of cones is radially offset from the other, relative to the longitudinal axis of channel 252, such that air passing through channel will contact a maximum number of cones 280, 282, 284.
The interaction of the cones 280, 282, 284 with the air passing therethrough prolongs an interface of the moisture molecules with the cones as well as the interface of an air stream with these moisture-laden cones. The air stream is produced by the breathing of the wearer. Accordingly, transfer of the moisture to the air stream is enhanced. In turn moistened air is discharged from the outlet 256 of the channel 250 into the primary chamber 210, through outlet 106 and into the oral cavity.
The cones 280, 282, 284 may be fixed within the first channel 212. Thus, a humidifier housing 250 is not needed. Alternatively, the cones are positioned within the channel 252 of housing 250. The number of cones may vary. The releasable friction fit of the humidifying housing 250 within the first channel 212 allows for different humidifier housings 250 to be used having different numbers of cones therein. Alternatively, a pair of cones may extend from a ring which can be releasably fitted within the primary channel 212 of channel 252 of humidifier housing 250 channel 252.
A fastener assembly 500 is slidable over the sleeve and against shoulder 222. The fastener 500 comprises a flexible bracket 502 with aperture 522 therein to engage the annular shoulder 222. An elastic band 510 is secured at its ends to apertures 524, extended above the ears and about the head of the user. Accordingly, the fastener 500 may be used where additional assurance of maintenance of the sleep aid device 10 within the mouth of the patient is desired.
It is here noted that the outer diameter of the sleeve 212 of primary housing 200 or humidifier housing 250 may be configured so as to be easily secured to medical tubes connected to downstream medical equipment. Thus, my device 10 need not be used alone but in combination with other medical equipment.
It is to be understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
